I'm still not sure if I want (NEED) to do a mass air swap before installing my sn93. Will the performance be the same with speed density ? I would appreciate all opinions. I'm not really interested in doing anything else to the motor except for the supercharger.
Stick with the SD. I recommend you don't go thru the headaches of converting. Mass air systems do adapt better to changes however. The MAF sensor is an inlet restriction = less HP. I am running SD on an '86 Mustang. I have a smaller pulley (3.75" Dia.) on the Supercharger and have had no problems. It actually seems to be idling better with the supercharger than w/o it!:)
I'm making ~350 horse on SD with stock 19 pounders and an SN93. My car has little stuff like an underdriven PS pump, 1.7 rollers with good springs, an off-road H and Flow 2 catback. On an absolutely stock good runner, it'll still get close to 300 horse. If that's solid enough for ya, plant it on there, hook up your FMU, do the MAP sensor mod and go.
